I know exactly what you are talking about! It is a type of mildew that grows on outdoor plants and trees aimlessly, yet remediable. Ortho puts out a mildew treatment you use in a garden sprayer. It worked for my lilacs and evergreen tree. You can find this mildew treatment at most garden centers in or near your town. Look for white powder mildew in the directions or list of what that product treats so you know you have the correct one. There are other brands that have treatments for this stuff, but I like Ortho. Not expensive either.Try the UC Davis link, it will explain in further detail.

Reply:Powdery mildew - caused by lack of ventilation, high humidity. I cured it on a plant of mine by using (yes, really) fresh coffee grounds sprinkled on top of the soil, watered in with beer. No kidding.





good luck
Reply:It's mildew, and any leaves with it are dead. I would reccomend you remove all the leaves you see with the dust on them, so it doesn't spread too much... if most of the plant is covered with it, then it is pretty much lost, but you may be able to get some kind of treatment. As a last ditch effort, you could try snipping it all down to the base and letting it start over.
